ンク給水用ボールタップである。The present invention was devised in consideration of the above, and its purpose is to provide a ball tap with a simple structure and low cost that prevents backflow even if negative pressure is generated in the water pipe. The structure is such that when discharging water, the diaphragm valve is pressed by the water supply pressure to create a gap between the valve seat and the diaphragm valve, and a gap is opened at a circumferential position with a larger diameter than the valve seat of the diaphragm valve. In a diaphragm ball tap, water is discharged from multiple through holes, and when the water is stopped, the buoyancy of the floating ball is expanded with a lever and the piston presses the diaphragm valve against the valve seat to stop the water. A ventilation valve seat having a communicating hole in the direction and protruding from the lower end of the piston, and a protrusion formed at the end where tap water flows into the chamber of the main body from the tank attachment part at a position opposite to the ventilation valve seat. This ball tap for tank water supply is characterized in that a diaphragm valve having a plurality of through holes protruding from the vent valve seat and a circumferential position larger than the diameter of the valve seat is provided between the valve seat and the valve seat.

本考案のボールタップは以上の如き構造により成るもの
で、次にその動作状態を説明する。The ball tap of the present invention has the structure as described above, and its operating state will be explained next.
今当該ボールタップを取りつけた洗浄用タンクに水が一
定量貯溜されていて浮き玉７が所定の位置に浮上して、
その浮力に依り第３図に示す如くピストン４がダイヤフ
ラム弁３を弁座１０に押しつけ弁座１０を完全に閉塞し
て止水する。A certain amount of water is stored in the cleaning tank to which the ball tap is attached, and the floating ball 7 floats to a predetermined position.
Due to the buoyancy, the piston 4 presses the diaphragm valve 3 against the valve seat 10 as shown in FIG. 3, completely closing the valve seat 10 and shutting off the water.

され給水が開始される。Next, the drain valve (not shown) of the tank is activated to release the water stored in the tank, and as a result, when the water level falls, the floating ball 7 moves down as the water level falls, and the piston 4 is moved through the lever 5. The valve seat 10 is moved backward relative to the diaphragm valve 3, and the valve seat 10 is opened to start water supply.

4, the water flows out from the outlet 15 to the muffling pipe 17, but the diaphragm valve 3 is pressed against the vent valve seat 21 provided on the piston 4 by the pressure and force of the flowing water, and the water flows out from the communication hole 19. Since the gap between the piston 4 and the cylinder 16 is also kept watertight by the U-shaped gasket 23, the flowing water is discharged only from the muffler pipe 17.
次にタンク内の水位が上昇すると共に浮き玉７が上昇し
、梃子５を介してピストン４を弁座１０方向に押してゆ

３を弁座１０に押しつけこれを閉塞し給水が止まる。Next, as the water level in the tank rises, the floating ball 7 rises, pushing the piston 4 toward the valve seat 10 via the lever 5, and when it reaches a predetermined water level, the screw!・N4 presses the diaphragm valve 3 against the valve seat 10 to close it and stop water supply.

７に負圧が生じる余地が除去される。As shown in Fig. 5, when water is supplied, negative pressure is generated in the water pipe due to a water outage, etc., and the water stops flowing. At the same time, the diaphragm valve 3 returns to its previous position due to its own elasticity, and the pressure difference between the front and rear sides of the diaphragm valve 3 This closes the valve seat 10 and creates a gap between it and the ventilation valve seat 21, and the chamber 14 and the muffler pipe 17 communicate with the atmosphere through the communication hole 19, so that the atmosphere is sucked in and close to the tank water level or Damaged silencer pipe 1
7 is removed.
この大気圧によってダイヤフラム弁３が弁座１０に押し
つけられる力は、流入口９側の負圧の大きさに比例する
。The force with which the diaphragm valve 3 is pressed against the valve seat 10 by this atmospheric pressure is proportional to the magnitude of the negative pressure on the inlet 9 side.
また負圧の大小にかかわりなくダイヤフラム弁３によっ
て弁座１０は完全に閉塞されているので、タンク貯溜水
が水道管内に逆流することはない。Further, since the valve seat 10 is completely closed by the diaphragm valve 3 regardless of the magnitude of the negative pressure, the water stored in the tank will not flow back into the water pipe.
以上の如く本考案になるボールタップは、ボールタップ
の止水、給水機能の他に、逆止弁機能と真空破壊弁機能
を兼ね備えている。As described above, the ball tap according to the present invention has a check valve function and a vacuum breaker function in addition to the water stop and water supply functions of a ball tap.
例えば弁座１０とダイヤフラム弁３との間に万一異物が

いると言え、しかも従来のボールタップと比べても部品
数は何ら増加せずその機構も簡潔であり、給水、止水性
能も劣る所はない。For example, even if a foreign object were to get caught between the valve seat 10 and the diaphragm valve 3, creating a slight gap and preventing the check valve from functioning, the atmosphere would be sucked in through the communication hole 19 and the outflow port 15
Since it prevents negative pressure from reaching the tap, it can be said to have a double backflow prevention function.Furthermore, compared to conventional ball taps, the number of parts is not increased at all, the mechanism is simple, and water supply and water stop performance are also improved. There is no inferior place.
またダイヤフラムを弁体として用いる為、自重により下
る型式のコマ型弁と比べその使用に方向性がなく横型ボ
ールタップに使用できる。In addition, since a diaphragm is used as the valve body, there is no directionality in its use compared to a top-type valve that descends due to its own weight, and it can be used in horizontal ball taps.
このように本考案になるボールタップは非常に優れた機
能をもち、且つその製造コストも低くできることからそ
の実用性が極めて高く、その公共衛生に益する所頗る大
である。As described above, the ball tap according to the present invention has excellent functions and can be manufactured at low cost, making it extremely practical and greatly beneficial to public health.
